Iressa (gefitinib) is a targeted therapy drug used to treat non-small cell lung cancer (NSCLC). It is a tyrosine kinase inhibitor (TKI) that works by blocking the action of certain proteins that are involved in the growth and spread of cancer cells. Iressa is used to treat NSCLC that has spread to other parts of the body and is not responding to other treatments. It is also used to treat NSCLC that has a specific genetic mutation known as EGFR mutation-positive. Iressa is a relatively new drug and is not widely used. It is approved in many countries, including the United States, Europe, and Japan. However, it is not approved in all countries, and its use is limited in some countries due to cost and availability. The Iressa market is highly competitive, with several companies offering similar products. Companies in the market include AstraZeneca, Pfizer, Merck, Bristol-Myers Squibb, and Eli Lilly.
